Who's right?

Hello,

After reading the paper "Color Management in Mac OSX" I finally got the idea behind the ColorSync filters. So far so good. Alas when I apply (in Preview) a filer for the Epson 2200 EnhancedMatte@2880 with intent relative, and the same setting in PS7 (black point compensation on), the respective soft proofs didn't match!. Certainly not by much but real.

Digital color measure reports:

PS7:
R: 232,102
G: 147,2245
B: 123,5102

Preview:
R: 211,6122
G: 139,6122
B: 116,1225

The source is an untagged RGB file. Who's right?

Also, when using Preview from PS before sending to print, when I use a tagged or untagged source and any of the Epson profiles, Preview shows the colors completely off (kind of magenta invasion). This remember me my early days with the Epson 2200 (under Windows) when I thought the preview of the Epson driver has any value beyond showing merely where on the page the image is going to be printed. But this time the warning is real! you're bounded to disaster if you hit the print button.

This behavior disappears when I use profiles with names like EP2200AMPEPNLHQST.ICM but can't find the media for which they are intended. Their space is CMYK which drive me crazy. Didn't the ink-jet raster printers be better "profiled" (characterized) as RGB devices?

It seems there are a lot of chapters of "color management" I missed...

Thanks,
